Authorities said the suspect also died after getting into a shootout with a responding officer, but it was not immediately clear if she was killed by a police bullet or a self-inflicted gunshot wound.

Update 2:05 p.m. EDT Aug. 20: Authorities have identified the person killed Monday morning in a workplace shooting at the Ben E. Keith Foods facility in Missouri City as overnight manager Francisco Reyes, KPRC-TV reported.

The suspected shooter was identified as Kristine Peralez, according to the news station. A third person suffered a gunshot wound to his leg.

Authorities are investigating social media posts Peralez made before Monday's shooting, Missouri City Police Chief Mike Berezin said Monday at a news conference. The Dallas Morning News reported they were also looking into comments she made to colleagues before the attack.

"I think (she) actually may have spelled that out for us," Missouri City police Capt. Paul Poulton told the Morning News.

Update 9:20 a.m. EDT Aug. 20: Authorities told KTRK the woman suspected of opening fire at the Ben E. Keith Foods facility in Missouri City was an employee who starting shooting just before 2:30 a.m. Monday in the facility's warehouse. At the time, between 20 and 25 people were working in the warehouse, Missouri City Police Chief Mike Berezin said Monday at a news conference.

Berezin said the shooting took place during an overnight shift. Two employees were shot, one fatally, according to KTRK. The surviving victim suffered a gunshot wound to his leg, the news station reported.

Berezin declined to identify the victims or suspect in the case or confirm reports from KTRK and KHOU that the slain victim was an overnight manager at the facility.

An officer confronted the shooter outside the warehouse Monday morning and fired at least one shot at the woman, but it was not immediately clear if the bullet hit her.

“Whether or not the shooter was actually hit by one of the officer's bullets or whether it was self-inflicted, we don't know at this point,” Berezin said.

The officer was not injured.

“The officer is doing very well right now, considering the circumstances,” Berezin said.

Authorities continue to investigate.
